| What is DotNetOpenMail? |
|
DotNetOpenMail allows you to send email from applications which use Microsoft's .Net development framework, including asp.net, C# and WinForms. It is a freely available open-source component written in C# that makes it easy to create HTML and plain text email with file attachments without needing the System.Web.Mail library. A programmer can use it to create multipart/alternative, multipart/related and multipart/mixed MIME messages in various character sets and various mime encodings such as quoted-printable, 7bit, 8bit and base64 without needing to know too much about the details. |
它是C#编写的开源组件，它不需要使用System.Web.Mail类库就可以容易的创建带附件HTML和Plain-text的Email。程序员不需要知道很多相关的细节就可以使用不同的字符集或不同的MINE编码来创建multipart/alternative，multipart/related和multipart/mixed的MIME消息。

"Odette de Crecy"));
emailMessage.Subject = "Missed you";
emailMessage.TextPart = new TextAttachment("Just checking where "+
"you were last night.\r\nSend me a note!\r\n\r\n-Charles");
emailMessage.HtmlPart = new HtmlAttachment("<html><body>"+
